小窑采空区积水探放技术及应用

Technology and application of water exploration and release in goaf of small kiln

正珠煤业21509回风巷掘进过程中遇小窑采动破坏区,小窑采空区范围、积水量不明确,严重威胁矿井的安全生产。本文利用“物探先行、钻探验证、物探与物探验证,长、短探结合”的探放水工艺,加强对小窑采空区积水的探放,消除了水害隐患,确保工作面安全掘进。

There are small kiln mining damage zone in the heading area of 21509 return air roadway of Zhengzhu Coal Industry,the area of small Kiln Goaf is unclear,the water quantity is unclear,which threatens the safety production of mine.In this paper,the water drainage technology of combining"geophysical prospecting in advance,drilling verification,Geophysical Prospecting and geophysical prospecting verification,long and short exploration"is used to strengthen the exploration and drainage of water in Goaf of small kiln,eliminate the hidden danger of water damage and ensure the safe tunneling of the working face.
